What is the area of the shaded region plzz help
Aneli [31]

Answer:

78.10 cm^2

Step-by-step explanation:

The area of the shaded region is the area of the rectangle subtracted from the area of the circle.

area of circle = (pi)r^2

area of rectangle = LW

shaded area = area of circle - area of rectangle

shaded area = (pi)r^2 - LW

shaded area = (pi)r^2 - LW

shaded area = (3.14159)(6 cm)^2 - (7 cm)(5 cm)

shaded area = (3.14159)(36 cm^) - 35 cm^2

shaded area = 113.097 cm^2  35 cm^2

shaded area = 78.097 cm^2

Answer: 78.10 cm^2

Prove that n is odd if and only if 3n + 6 is odd by contradiction.
Reil [10]

Step-by-step explanation:

o - odd number

e - even number

n + e =o, if n is odd...rule 1

n + e = e, if n is even...rule 2

n × o = o, if n is odd...rule 3

n × o = e, if n is even...rule 4

thus if 3n +6 = o,

then 3n must be odd, following rule 1

=> 3n = o, then n is an odd number, following rule 3
